Re: What do they know?
afaik, if the quantum computer was anywhere close to its theoretical performance, 2048 bit keys would still be ridiculously short....
Re: 32GB of books?
When it comes to text books, one hardly needs higher resolution than the current Kindle offers.
I'd imagine that Kobo's high resolution screen would impress manga/graphical novel readers in particular. Those do need the extra storage.
As interesting as the title seems, just looking at the graph shows that the *dreaded* memory effect is in fact minuscule in Li Ion batteries.
Talk about blowing a story out of proportion. Among the problems facing Li-anything batteries, memory effect is hardly worth mentioning.
Re: Pierre, I noticed that the general public is very prone to parroting any 'seemingly true' facts about technologies they don't understand. Do yourself a favor and check some actual research before believing everything in your first google search.
Re: hevc facts
The key is in multicore & multithreaded hardware based decoding. If you ran a purely CPU based, software single-threaded (i.e. reference) decoder, you'd get nowhere near realtime decoding for full HD streams even using h.264/avc, not to mention HEVC.
Nobody sane does that, though - and today's CPUs and GPUs are proof of the fact, many supporting full decoding of h.264 using specialized instructions or dedicated HW. The real issue is going to be power-efficient encoding of h.265 streams in hardware, because there's no cheating the complexity even with specialized ASICs.
There is a broad alliance of patent holders behind h.264 and even broader behind HEVC. The difference that HEVC made was including HW and SW partners, so that it could be designed for easier processing using combinations of CPU/GPU. Also, the design goal was to produce a codec @ half of h.264 bitrate - this was close, though not quite there last time I checked a couple of months ago (while the reference codec was in Working Draft 6).
As for UHD content, there are suddenly large swaths of similarly textured areas in each frame (imagine a DSLR shot of someone's peachy complexion) - all the more suitable for larger quadtree-style macroblocks. The large resolution also calls for finer motion-estimation, which is responsible for a lion's share of the encoding complexity increase - actual "compression" in HEVC has been pretty much ported from h.264/avc, and this also means that developing solutions for h.265 is going to be that little bit easier.
For people unfamiliar with the process, a compression standard pretty much describes the format of a data stream - and leaves the actual implementation to the market. HEVC working group was actually kind enough to also provide a reference encoder/decoder software, modifications of which made its way into many scholarly papers and dozens computer science students' graduation theses.
The sad truth about free codecs is that the basic technology for video compression hasn't changed significantly since mpeg2 - and the elements in that are very much patented. VP8/9/10.... won't be any different.
last minute check
I seriously urge NASA to use these last 40 days to re-check which part of the whole shebang is expecting its input in fractions of imperial units. Considering the thing was built and operated by engineers such as the one interviewed here, there's high probability of a non-metric bug stuck somewhere in the middle. Hopefully, it's not a 21 ft rope gently dropping the buggy from 20 m above surface...
holding his head
Anyone else thought of a (nearly) headless Nick?
I was just wondering how on Earth could he still talk....
Re: you still use optical drives?
Just to keep you up to date: OS X no longer comes on rotating plastic. Since introduction of coffee holder-free MB Air, Apple has switched to cute own-branded USB keys. You can even upgrade your installation "media" this way when a new breed of cat comes around.
As for Creative Suite - Adobe offers complete trial downloads, which can be turned into full software by entering the proper serial number. (Yes, they still provide plastic, but I haven't actually opened my CS6 package except to get the code).
Quark - oh, well.
Re: Bluetooth LE
If only those sensor companies hadn't gone for ANT+...
Lack of options
For the price tag attached, I'd much rather become a fruity fanboi - even Apple understood that resolution is king when people pay this much for a computer today. Not having an SD card reader is just rubbing it in; the only thing going for the Dell is its USB 3 port.
Though personally, I'm waiting for the retina display in the next-gen Air.
screen backlight and distractions
I've read many a book on my veritable Palm 3e's good old grayscale LCD, alternatively backlit with Indiglo. While it now rests in electronic heaven, I routinely got up to two weeks of joy from a pair of AAA cells.
Although I couldn't care less for the author's attitude, I'm also a somewhat satisfied Kindle customer. Extolling the virtues of a passive reading screen to an opinionated crowd would be a completely moot point, so I'll mention another, often sidelined 'feature' of dedicated ereaders - their intentional lack of any other functionality.
While many smartphone users will argue that they can just as well use their 'precious' to read, I find having so many features at hand a huge distraction. It may be just my personal opinion, but know at least two other Kindle owners who think alike.
That said, the entire publishing and media industry should pull their collective heads out of *where the sun don't shine* and bring a reasonable offer on the table. Just how long will they continue to ignore that end users no longer perceive geographical location as the critical factor, especially when purchasing bundles of 1s and 0s.
Many find the 2D solar parks hideous enough, care to explain how much opposition would these "beauties" gather once built anywhere near populated areas? Surely the efficiency would be at least 5x higher....
Re: Re Grays?
Wikipedia is your friend...
To sum it up, Gray is the less discriminating unit = radiated energy/mass
Sievert is exactly the same thing, as long as the radiation is Gamma rays. Other types of radiation, namely alpha & beta can have significantly worse effects on tissue, and therefore include a coefficient, which compares them to an equivalent dose of Gamma rays.
Thankfully, alpha radiation is generally easy to stop, so unless one gets a source inside his body, (remember Litvinenko in 2006?) one should be relatively safe.
USA a free country?
With the current legislation, China is much more a land of the free than the venerable US of A.
The US like to tout democracy as the ultimate freedom, but apart from their right to vote, the average chinese person does indeed have much fewer obstacles in their life. Travelling to the US? Prepare to be searched, questioned, probed, groped, scanned and have your entire notebook copied/confiscated, all at the liberty of the omnipotent TSA. If you go to China, you might be refused a visa, but the entry is much more pleasant.
Now which is the land of the free?
Computers vs Humans
Sorry to pee in your cornflakes - this is exactly the reason why serious crackers have rainbow tables and dictionary files.
The WPS button is unfortunately only one of possible connection modes under WPS. Others rely on a matching "PIN" - which obviously limits the effective security level of the device. This was intended for devices without a HW button, but it seems that it was an even worse idea than buttoned WPS.
The patent-free dream
As much as I'd like to applaud the developers' intention to start with a new, patent-free design, most of the currently known video and image compression techniques, including e.g. motion compensation, prediction and entropy coding are sadly all patented by the current MPEG-LA members and/or others.
It would be extremely unlikely for a team of developers to come up with a completely novel approach to video compression, especially if they are well versed in the current technology and therefore blinded by the known approaches.
The minefield provided by current patents in the area is nearly impossible to avoid, as proven by projects like VC-1 (which, sadly, resembles most modern codecs to the minute detail).
Printer memory, not USB
That's 128 MB of printer memory, not a USB stick. The price is still outrageous for that one, but at least it is a bit more exotic.
daft storage decision
The asinine decision to provide so little storage while denying memory card expansion rightly cost this device a slew of customers. Seeing as most smartphones today need to be tethered to the power grid just about every day, it appears deranged to force customers into the cloud for their media files, too - wasting expensive bandwidth and precious mAhs on 3G. Not to mention potential customers living in areas with patchy wireless coverage.
For a phone that is supposed to increase WP7's market penetration, MS's business decisions remain rather unfathomable.
The key word here is accountability.
While it is true that Spamhaus doesn't block anything, but its market penetration is so large, that it has enormous influence without any sort of accountability. That is a BAD thing, evidenced by the bullish behaviour described in this article.
You attempt at giving Spamhaus a carte blanche, since it's "your ISP's choice", is flawed from its very conception. Once you find your company mail server's IP blacklisted, and happen to lose business because of it, you'll start to understand my opposition.
Spamhouse has a lot of clout, yet there are no clear guidelines saying how far they can go. This is a position open to all sorts of political influence and I'd hate to put so much power to a body which clearly lacks ethical standards and can lower itself to the described behaviour.
Re:e-books .... mobility
Try stuffing 3-4 paperbacks in your luggage whenever travelling, you'll notice the difference. Paper takes up a lot of space and I certainly like looking at my Discworld series collection, all lined up on the shelf. But alas - currently, it is about 9000 km from me, because I simply couldn't rationalize stuffing kilos of paperback fiction in my luggage when going abroad.
That said, I certainly prefer reading textbooks and technical literature on paper (scribbles, squiggles, and just plain old visual memory). It's just all the other fiction, novels and even news articles are so much more convenient when contained in a slim 240 g package.
At the risk of sounding like a proper nerd, I object to the neologisms used in the header and subtitle of the article. While glad to see liberal use of English on The Reg, it is generally done with taste. "Flava" and "mobe" hardly fall in that category.
I clearly remember seeing 3D footage from space in an IMAX several years ago. How come that doesn't count?
The orange flying in my general direction through the ISS and out of the screen was a rather memorable event, definitely 3D.
The drive seems to have some annoying firmware issues Seagate has been very slow about despite a series of firmware updates.
On many computers, this drive will cause the system to stutter intermittently, which is particularly noticeable if you watch videos. While this can be mitigated by disabling the drive's APM (thanks, quietHDD), Seagate should really be able to do something more efficient, which doesn't seem so much like a hack.
I do like the drive's performance, although I tend to leave my PC on for extended periods of time and don't really see the "fast boot" very often. It can be very fast loading Photoshop, but part of that achievement is down to my 6 GB of RAM and Win7's preloading.
Generally speaking, yes the performance improvement is noticeable. But there are still issues which would make me reconsider going full-ssd if I was buying again.
As anyone working with audio on computers would have noticed, adding a new audio device to the mix does not mean that it automatically picks up everything.
As an example, designating your onboard audio device for communication (win7) means that any blurbs created by skype et al. do NOT go to your Hi-Fi setup over the air at all.
What's more - if your favorite music app packs any grit, it will let you select the audio device you want it to use, instead of going for default.
If you were interested in connecting to your hi-fi, you should have turned off any and all system sounds anyway.
University hardly a Challenge?
I beg to differ, in my own personal experience, a lot of Uni students (particularly CS majors) appreciate portability and battery life, rather than luggability and mains tethering.
I guess other majors might beg to differ, especially if most of their studying is done using pen & paper, but unless the grant also commands a set of wheels, this one is going to remain a foldable desktop.
You, sir, appear to have completely missed the main point Tim Worstall was making. He never said getting the rare earths is technically impossible, just that it is - at this time - utterly economically unfeasible.
Not only would it take more money to extract the rare earths at the detected concentration than their current worth on the market, but you also have to deal with the byproduct - billions of tons of acidic silt.
Dumping them into the sea would bring any and all Greenpeace armour to the mining site with destruction of mining equipment on their minds.
Therefore, unless China completely cuts the rest of the world off their rare earths supplies, causing their prices to skyrocket, there is no way to make money off that silt.
Anybody attempting to do so would need to find a lot more valuables in the dirt - perhaps not just rare earths.
I remember visiting Miraikan in Tokyo back in 2002 and there was a distinctly similar interactive globe made from LED panels already.
I applaud the upgrade to OLED panels (and the upgrade in resolution), however the idea is hardly new.
True, but Kindle owners would hardly feel pressed to buy another ebook reader. The "choice", as pointed out, stands for other classes of devices, meaning your PC, your tablet-smartphone and your Mac.
DRM might be a hassle, but since there are applications which allow you to read the protected books on other non-ereader equipment, you certainly have some choice. Just the ereader has to be courtesy of Amazon, and Kindle is incidentally one of the best ones on offer, especially with the free worldwide 3G package.
While I'm not very happy with Kindle's obstruction of DRM EPub, especially in light of possible library loans, I do understand Amazon's wish to protect its market share. Besides, publishers do not seem too eager to allow electronic library loans any time soon.
not entirely wrong, just a bit
You are mixing pears and apples - the gripe ISPs have with YouTube et al is that it overloads their expensive trunks to the rest of the world.
In comparison, Gaming on demand, just like IPTV, is a solution located at ISP premises, or at a specialized location with separate high bandwidth connection. What's more, it offers a source of revenue for ISPs, unlike bandwidth sucking YouTube.
That said, I do not see how the service can overcome the deadly latency, which makes it entirely unsuitable for action gaming. I imagine quite a bit of the advertised 50ms is spent encoding the H.264 video, and the marketers presume everyone lives in a fiber-connected urban setting. Sadly, for many in Europe, US and the rest of the world, that is not the case.
Re: Does anybody not see the problem?
You need to let your imagination run a little. People often mistakenly assume their home network is safe, as long as they use WPA2 (that's for sophisticated users, who have actually heard of WPA2). Hence, resources like home computers, home network storage, etc. are often perilously unsecure.
If someone wanted to plant something illegal onto your computer, or pilfer your documents, license keys, compromising private pictures or other valuable data, there would often be very little to stop them once they compromised your WiFi security. And the best thing - you would never know!
Never underestimate malice, jealousy or just plain envy when it comes to motivation.
And how exactly is Amazon supposed to know?
Your argument seems flawed, dear Watson.
Amazon rents its cloud oomph to clients independent of what they want to use it for. Sure, there may be some official policies against illegal stuff, but unless someone takes some serious time and effort to debug every single program executed on the cloud, there is no way for Amazon to know just what is their fluffy stuff is being used for.
I reckon that Amazon might publish a policy update sometime soon.
100M per month, not every day
the writer seems to have misunderstood the data plan offered with chromeOS devices.
the presentation, however, mentioned a rather measly 100M/month instead. This may sound more open while avoiding a serious lock-in, but it also means the additional $10 charge per month will become almost mandatory.
one thing I'm not going to get anytime soon.
If the functionality of my "new" notebook is going to depend on 3G signal reception, then I might as well forget it in the near future (3-5 years minimum). There are so many places that barely have 2G coverage that the idea is as ridiculous as depending on Google Navigation to actually get you somewhere.
Unless you spend all your time in an exceptionally well covered city.
Poor source quotation
The original NASA article mentions the peak's altitude is relative to Moon's "mean radius", which would have cleared up a lot of the confusion here.
In fact, GPS and the likes also use an approximation through a hypothetical ellipsoid of the Earth's surface, not actual sea levels, which are rather difficult to stabilize. Google/Bink/Yahoo WGS 84 to read more.
how about supporting existing BT handsfree sets?
The Android handsets have mediocre support for SE's own existing BT headsets - I would really love to see the song title again on my MW600, something every stupid SE phone with bluetooth could do any time of day.
As mentioned above, it has much to do with the construction of the camera involved.
Consumer digital cameras (except for Sigma's Foveon) employ an interleaved (Bayer) color pixel matrix, which requires extra processing to create a full color image, that doesn't in fact have quite the effective resolution touted by its manufacturer.
Foveon and most high-tech/high res cameras use separate full resolution sensors for each color, so the resulting image is just a composition of the separate color images on top of each other.
The disadvantage of this process is the time delay between the capture of each color, which manifests itself as "rainbow patterns" in moving objects.
The camera involved in this image indeed has a very short delay between the color separations, so the effect doesn't show up very often, but an airplane moving at 800kph is just too big a challenge.
PS: the separate sensor idea is simplified to prove a point.
While I'm sick of this software patent mayhem US of A has wreaked upon us, I concur that VP8 is frighteningly similar to H.264 in the patent-covered areas, meaning google's probably got some interesting times ahead.
With the amount of money MPEG-LA are looking to lose out on VP8 if it succeeds (and when they finally raise interweb H.264 license fees like the arseholes they are), M$ et al. are unlikely to back off either.
Litigatious departments report in full gear!
The benefit of the deep buffers is in handling momentary spikes, which are often observed on individual machines.
When such spike occurs, it is buffered, while the egress line continues handling the data at its maximum speed, provided the scheduler can keep up. With deep buffers, even very large spikes can be handled without affecting the clients and without requiring retransmission of packets dropped due to congestion.
The deep buffer cannot do anything for your hypothetical 1Gbps traffic through 100Mbps line bottleneck if the source keeps sending data at a uniform 1Gbps. If this is the case, you simply need to buy more bandwidth.
The solution presented by Force10 aims at handling traffic that fits within the available bandwidth most of the time, while allowing for occasional (although fairly large) traffic spikes that don't. As the buffers help avoid congestion, packets do not need to be retransmitted (lengthy process), they simply sit in the queue looking pretty and await their turn at the line, while the traffic simply suffers from a bit of delay.
Re: plastic tie ?
I'm pretty sure the plastic tie is more effective than frozen-solid duct tape with its space-temperature intolerant rubber style adhesive.
They ought to make a space-capable NASA tape, too, though.
Ken Tindell, ego much?
With the sheer amount of computing power in modern cars, I'm surprised the study seems to be the first of its kind.
Even Hollywood has noticed that cars (planes, ships, spacecraft...) are prone to hijacking via digital and certainly, if there's will, there is way.
What shocks me though, is the completely ignorant stance of Ken Tindell, a man who is supposedly in the loop.
Given the minimal amount of public peer review (WEP anyone?) these systems obviously receive, it is the proverbial timebomb sitting in your garage and waiting for someone with vested interest and sufficient resources to stop by and light the fuse. Or disable your brakes.
pot calling the kettle black
Google crying foul over privacy concerns? Now I've heard it all.
Neither of the two companies care one bit about the privacy of their users, the announcement being merely a marketing ploy in an attempt to lure F users to G's version of social goodness.
One significant difference remains, though - in posting on Facebook, (hopefully) most users understand they are sharing information, while the Google approach is to share bits and pieces that were never intended to be broadcast to the world in the first place.
